Not to take away anything from this project (which looks pretty cool), but for folks using KDE on Linux you have a similar launcher built in called Krunner (Try Alt+F2). It is pretty well integrated and has a nice ecosystem of plugins.
Posting this primarily because I frequently run into people who use kde but have never used krunner.
I found Krunner entirely by accident after switching from Windows. PowerToys has a quick launcher that's triggered with Alt+Space. Used the shortcut out of habit after switching to a KDE environment, and was pleasantly surprised to see a similar interface pop up!
